“I could be having the worst day of my life, hate my body, think I’m fat, think I suck, and as soon as I hear the first few notes of my intro, that all goes away,” the 21-year-old pop star told Billboard. “Everything that I hate about myself goes away when I walk onstage. That’s why I cling to it so much — it keeps me from killing myself.”

As Justin Bieber‘s pal revealed, she was not only diagnosed with bipolar disorder during her senior year of high school, but spent part of that time in a psychiatric hospital after attempting to take her own life.

“I had tried to kill myself. I was an adolescent; I didn’t know what I was doing,” she said. “Because I was 17, I was still in a children’s ward. Which was terrifying. I was in there with 9-year-olds who had tried to kill themselves.”

“There was no TV, no music, no nothing,” Halsey continued. “The day I got out of the hospital I was in the car and I was listening to Imagine Dragons. It was a f—–g moment for me. I don’t think I realized how important music was to me before that.”

While Halsey’s career is just getting started, the “Colors” crooner also shared which outspoken artist she admires most.

“I love Kanye West,” Halsey gushed. “I think he’s a visionary. He’s one of those people for whom I separate his personality from his artistry.”

“But I also sympathize with him in a weird way, because being a musician is tough. If you were asked to talk about yourself for six hours a day you would probably go crazy, too! Which is why I give Kanye the benefit of the doubt. Being him must be so exhausting,” she added.
